ChemWhat Conductive Circuit Pastes & Conductive Shielding Pastes: A Material Platform Built to Print, Stretch, and Shield (Video)

Smartphone antennas, automotive defrosting circuits on panoramic roofs, wearable ECG electrodes, and EMI shielding in telecom base stations all rely on the same category of material: conductive paste that prints, sprays, or molds like ink. This is where ChemWhat’s two product lines come in — conductive circuit pastes and conductive shielding pastes. On the circuit side, ChemWhat’s low-temperature silver paste cures at just 80–90°C, survives 5,000+ abrasion cycles, and holds 4B adhesion after 1,000+ hours of 85°C/85% RH aging. For FPC boards and touch sensors, screen printing reaches 60-micron lines, and laser etching pushes below 30 microns. A dedicated stretchable silver paste withstands 2,000+ cycles at 30% elongation, keeping wearable electrodes and roof-glass heating circuits intact under repeated flexing. The portfolio extends further — solderable low-temperature paste, low-temperature sintered antenna paste, nanoimprint and PEDOT:PSS transparent conductive ink for transparent antennas and touch electrodes, plus termination pastes for capacitors, resistors, and inductors — 18 product categories in total, spanning consumer, automotive, medical, and IoT electronics. On the shielding side, ChemWhat’s silver, silver-aluminum, silver-copper, and nickel-carbon shielding pastes spray directly onto housing interiors, delivering up to 110 dB of shielding across 0.3–20 GHz. For seams needing both sealing and conductivity, silicone-core conductive gaskets and elastomeric connectors operate from –55°C to 160°C and survive 25,000 compression cycles without cracking. FIP nickel-carbon gasket adhesive extends shielding into tighter, more intricate spaces. These materials are already validated in 5G base stations, aerospace, rail, and EV applications. Behind this performance are two proprietary technologies — flexible printing for micron-scale patterning, and elastic shielding for durability under repeated deformation — backed by joint labs with global universities and research institutes covering formulation, simulation, reliability testing, and failure analysis. With fast delivery, responsive service, and custom formulation support, ChemWhat is a trusted materials partner across consumer electronics, wearables, automotive, 5G, and aerospace.
